This test auto-discovers the owners of SHM segments, monitors the usage of each segment, and reports the number of SHM segments owned by each owner, the number of segments mapped to/not mapped to processes, the count of processes attached to the segments, the total size of the SHM segments owned by each owner, and the number of SHM segments removed, cleared, and locked for every owner. This way, the test points to those owners with SHM segments that are not even mapped to any process, leave alone being used; thus memory segments that are candidates for removal/release can be identified.

This page depicts the default parameters that need to be configured for the IpcsSharMemTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• By default, the REPORT BY flag is set to Owner. This implies that, by default, the test metrics for every message queue owner on the target server. You can set this flag to Total, if you want the test to report metrics for the Total descriptor alone; in this case, the test will aggregate measures across all the message queues on the server. Alternatively, you can pick the Owner and Total option. In this case, the test will report metrics per owner and also for the Total descriptor.

• The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

• Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
